WHAT IT DOES

What export_hook_script does on Jshookmcp

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs export_hook_script safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Jshookmcp, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For export_hook_script, this is the rule to start with:

export_hook_script Rate-limited

export_hook_script stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

The button opens the PolicyLayer dashboard: create your workspace, connect Jshookmcp, apply this rule, and every export_hook_script call is checked against it from then on.
